1. Lesson 3 Living in Water: Dwarf African Frogs
Question: What will the frog need in its habitat to survive?
Hypothesis: Use the Animal Background sheet to predict what the frog needs.
Dwarf African Frog Habitat Proposal
Draw and describe your ideas for the dwarf African frog’s classroom home. 1

2. ANALYZE: What are the elements of the dwarf African frogs’ habitat?
Natural Habitat
Classroom Habitat
Fresh water
Dechlorinated tap water
Space to live in
A tank
Plants
Elodea or
Food
Fish flakes
Rocks, soil
Gravel
Light
Natural light
Air
Classroom air and tank water
TG 24

5. Distribution Center for students to make habitat
For each team:
1 Tank with lid
1 Ruler
1China marker
Pails of water
1 Large cup with lids
2 Small cups with lids
Paper towels
2 cups of gravel
spoon

6. Build the dwarf African frog habitat and illustrate.

7. Schedule
Feed once a day. If there is food visible, remove it with the spoon to avoid water contamination.
Reduce amount of food fed if food visible when time to feed again.
Check water level, add new water every other week by removing 2 cold cupfuls of water and replacing it with 2 fresh cupfuls.
Ideal temperature is between 77 and 86 degrees.
If water becomes cloudy or algae occurs, empty tank water by placing frogs and plant in holding pail of conditioned water while cleaning habitat. Use paper towel to remove algae, and rebuild habitat.

8. Feeding Observation 1. What happened when you put food in the tank?
2. Did all the frogs respond to the food? What happened when you moved the food with the spoon?
3. How much food did the frogs eat?
4. Did the frogs eat from the surface or bottom of the habitat?
**You should observe the feeding carefully and discuss the above questions each time.**
